My present invention relates to domestic water supply apparatus, has particular reference to connections for supplying watenfor drinking and cooking.

The water supply for household use. frequently contains a high percentage of solid matter, either because the water is not suniciently filtered or because the house pipes themselves are old and rusty. The use of charcoal and similar filters is l0 well-known, these filters being usually connected in the iiow line, in the caso of large filters, or attached to the faucet, in the case of small filters.

Large iters have been found objectionable, due

to their initial cost and to the difficulty of cleaning or replacing the lter material. Small lilters are also dini-cult to thoroughly clean, and

are usually of a relatively inefficient type. It is the principal object of my invention to devise a filter construction that is quickly installed, is

inexpensive, is eflicient in operation, and is easily and expeditiously cleaned. To this end,

have devised a combination filter and faucet,

which may be readily interchanged for the house 2 faucets now in use and which need nc-t be removed for cleaning.

With the above and other objects and advantageous features in view, my invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more specifically defined in the claim appended hereto.

`In the drawings,

Fig. 1 is an elevation of the novel construction;

Fig. 2 is a section thereof on the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary detail, similar to Fig. 2, showing the filter control valve in reversed position;

Fig. 4 is a vertical section, parts being broken away, through Fig. i;

Fig. 5 is a detail fragmentary view showing the filter chamber outlet; and

Fig. 6 is a section the line ii-i of Fig. fl.

Referring to the drawings, the casing Eil includes a lower flow portion ll and an up er filter section l2. As more clearly shown in Fig. Il, the flow portion li has inlet connection which is adapted to be secured. to a water supply connection by means of a union of standard type, this inlet connection communicating with a ow passageway lli which terminates in an outlet nozzle l5. The flow portion ends in a valve housing i6 which has a hand operated faucet valve ll of usual type mounted therein to control the 'communication of the flow passageway with the'outlet nozzlethe' faucet valve having abarrel portion l which is threadedly mounted in the casing, and a closure gasket l@ 5 adapted to .engage the end of the flow passageway when the faucet valve is in closed position. The faucet valve has the usual end packing 2Q and end washer 2l, held in place by a removable cap 2E which screw threade'dly enga-ges the end l0 of the valve housing.

The filter section l2 includes a container 23, which is preferably of cylindrical form and open at the top, and which may be cast integral with the flow portion. A lter element 2t is mounted 15 in the lter section, and comprises a lower annular plate 25 having an integral upwardly positioned spider 25, an upper disk plate El, and two concentric perforated shells 28, 29 between which a textile' or other lter material 3@ is 20 mounted, the filter element being locked together by means of a central bolt 3l which passes through a central opening 32 in the spider and threadedly engages a central hub 33 of the disk plate. 25

The annular plate 25 has a recess 34 in which a packing ring 35 is mounted, and the lter member is locked in position in the container by the container cap 36 which threadedly engages the container and has a central boss 3l 30 pressing against the disk plate.

Referring now to Figs. 4 and 5, the flow portion has a tapered valve seat 38 cut therein, in

which a tapered valve 39 is mounted, the valve stem lo extending through the base of the flow 35 portion and having a handle ll secured thereto, and being packed in the usual manner by packing t2 seated in the usual recess and secured by a fiange nut t3. The tapered valve has two ports, 44, l5 formed therein, the port lili being a three 40 way port with passages L36, ll and llt, and the port l5 being a groove type port. The passage d8 is vertical, and communicates with the filter section through the interior of the annular disk 26, and the passages 36, lll are adapted to selec- 45 tively communicate with the inlet portion 49 of the flow passageway and the outlet portion 56 thereof. The lter section has an outlet chamber 5l which communicates with the space between the container and the filter element, and 50 the port i5 is adapted to selectively communicate the outlet chamber 5l with the outlet portion 551 or the inlet portion 49.

The operation of the novel apparatus may now be explained: 55

The water entering the flow passageway, see Figs. 2 and 4, passes upwardly into the space within the lter elements, through the filter element to the space between the element and the container, and thence out the outlet chamber to the outlet nozzle, where the flow is controlled by the valve l1. To clean the filter, the valve 39 is turned to the position shown in Fig. 3; the inowing water now passes upwardly through the chamber 5|, through the filter element in reverse direction, and out through the central port 48 to the outlet nozzle. The filter element is readily removed and replaced by removing the container top, and the filter material is quickly changed by separating the lter element parts. When removing or inspecting the filter element complete stoppage of flow is obtained by setting the tapered valve so as to position a solid portion of the tapered valve, preferably the portion between ports 46, 45, across the inlet portion 49 to close the same.

If desired the construction may be modified to have both hot and cold water enter the flow passageway, by using connections of standard type; but it is preferred to utilize a separate lter for the hot and the cold streams, and join the outlet portions of the two flow passageways by a swinging nozzle of standard type, thus eliminating the time interval involved in waiting for the necessary outflow of Water from the filter where changing from hot to cold, and vice versa.

While I have described a specific constructional embodiment of my invention, such changes in form, in arrangement and in dimensions of the parts, may be made as appear desirable, within the spirit and the scope of the invention as dened in the appended claim.

I claim:-

In a combination, a casing having an inflow conduit, an outow conduit, and a control flow opening in the bottom wall thereof and a flow passageway in the side thereof, said casing having a removable top, and a removable filter frame therein comprising a lter resting on said bottom wall and in the path of flow of fluid between said control opening and said flow passageway, and a plug valve in said control ow opening having ports for connecting said inflow conduit to said control flow opening and said flow passageway to said outflow conduit, and movable to alternatively connect said inflow conduit to said ilow passageway and said control opening to said outflow conduit.
